Adapty, made by Adapty Tech Inc., is a subscription backend for mobile apps. It gives developers an SDK (software development kit, a code library added to the app) for iOS, Android, React Native, Flutter, Unity and other platforms. Its servers validate each purchase with the app store and keep the user's access level in sync through renewals, cancellations and billing problems.
A paywall is the screen that offers the subscription. Adapty's drag-and-drop builder creates paywalls and onboarding flows that change without an app update, and A/B tests compare prices, paywalls and flows on split traffic. Revenue analytics show live revenue, MRR (monthly recurring revenue), churn and conversion, with predictions of LTV (lifetime value, the revenue a subscriber brings over time). Subscription events and revenue can be sent to other tools and back to ad platforms.
Adapty is a hosted service with open-source mobile SDKs. The standard self-serve plan is free below a monthly revenue threshold and then takes a percentage of tracked revenue; large apps get custom Enterprise pricing.
